Abstract

<P>PROBLEM TO BE SOLVED: To solve the problems that two actions of placing a foot on a footrest plate on a footrest base and fixing the foot by a fixing band are necessary and complicated, improvement still remains in eliminating a large space in the vicinity of a toe part of the footrest base and obtaining the sense of identity between the foot movement and a board movement, and the cost is increased since the footrest plate is separately provided. <P>SOLUTION: In a structure of a board part of a water walking tool with a hard material such as a plastic being covered around a foam material, a foot supporting part is provided on an intermediate portion of a board. A fitting part to be fixed to the board part is provided on a front end of the foot supporting part. A toe supporting part is provided at the position opposing the footrest base of the board part. Further, a toe supporting part is molded of a resin so as to cover a toe, and the foot supporting part is attachable/detachable to/from the board part. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a water walking device that can be worn on a foot and can walk or slide on the water by itself, like skiing.

  Conventional water walking equipment is a board made of foam material such as urethane foam, and a board part made of a hard material such as plastic enclosing gas or a board part covered with a hard material such as plastic. There is known a structure in which an opening for inserting a foot is provided in an intermediate portion of the board).

  The structure of this board is a structure in which the board is divided into a front part, an intermediate part, and a rear part, and a combination of foam materials molded in advance with a mold is joined together. In addition, the middle part has a footrest in the center, a footrest plate is installed on the footrest, and there is a fixing band on the side of the footrest plate, so that the player's ankle can be fixed Yes.

  However, in such a structure, two operations of placing a foot on a footrest plate on the footrest and fixing the foot with a fixing band are necessary and complicated. In addition, there is room for further improvement in that there is a lot of space near the toe portion of the footrest and a sense of unity between the movement of the foot and the movement of the board is obtained. Furthermore, the footrest plate is a separate part, and there is a problem that costs increase.

  In order to solve the above-described problems, the present invention has a structure in which a foot support portion is provided in the middle portion of the board in the structure of the board portion of the water-walking device in which a hard material such as plastic is covered around the foam material.

  It was set as the structure which provides the fitting part fixed to a board part in the front end of the said foot support part.

  The foot support portion is provided with a toe support portion at a position facing the footrest of the board portion.

  It was set as the structure currently shape | molded by resin so that the said toe support part may cover a toe.

  The foot support part is structured to be detachable from the board part.

    Since this water walker has the above-described structure, the complexity of the two operations of placing the foot on the footrest plate on the footrest and fixing the foot with the fixing band can be eliminated. In addition, when the toes are appropriately fixed to the toe support portion, a sense of unity between the board and the foot can be obtained and the operability is improved. Furthermore, the provision of the guide surface makes it easy to attach and detach the foot support member 1 and provides an excellent effect of reducing the cost because a fixing band is not required.

  1 to 4 show a board portion of a water-walking implement showing an embodiment of the present invention. FIG. 1 is a perspective view showing the entirety of a water-based walking implement showing an embodiment of the present invention. 2 is a cross-sectional view taken along the line AA in FIG. FIG. 3 is a perspective view showing a foot support member provided at an intermediate portion of the water walking implement board of FIG. 4 is a cross-sectional view of the toe support portion of FIG. 3 in a direction perpendicular to the board traveling direction.

  As shown in FIGS. 1 and 2, the water walking implement according to the present invention forms the board front part 5 by fitting the right board front part 51 and the left board front part 52 with different lengths.

  The board middle part is composed of one part, and a footrest base 3 is provided at substantially the center of the board middle part 6 and a foot support member 1 for supporting the foot is detachably provided. The board rear part 8 is configured by fitting a right board rear part 81 and a left board rear part 82 having different lengths.

  The board front part 5 is provided with a hollow part 53 and the board rear part 8 is provided with a hollow part 83. The hollow portion 53 and the hollow portion 83 are provided with vinyl or rubber floats (not shown) so that buoyancy can be maintained.

  9 is a keel. The keel 9 takes into consideration the straightness and lateral stability of the board. The keel 9 uses a hard resin and has a T-shaped cross section. The keel 9 is attached to the bottom surface of the front part of the board, the central part of the board, and the rear part of the board.

  3 and 4 are perspective views showing the foot support member 1, and a two-dot chain line indicates the position of the foot on the footrest provided on the bottom surface of the middle portion of the board. The foot support member 1 of the board intermediate part 6 is provided with a toe support part 4 at a position facing the footrest 3 of the board part. The toe support portion 4 is bent so as to be slightly larger along the shape of the toe, and is shaped so as to hook and support the toe and fix the foot.

  The entire foot support member 1 is integrally formed of resin, and a guide surface 11 is provided on the side surface along the longitudinal direction of the opening 7 of the board. The fitting portion 2 is provided at a position facing the front end portion of the opening 7 of the board.

  The foot support member 1 is structured to be detachable from the board portion. When the foot support member 1 is mounted on the board, the fitting portion 2 of the foot support member 1 is inserted into the front end portion of the opening 7 and the guide surface 11 is rotated along the inner side in the longitudinal direction of the opening. Go.

  When manufacturing this board part, first, the right board front part 51 and the left board front part 52 are injection-molded using a mold. The right board rear part 81 and the left board rear part 82 are formed in the same manner. Further, the central portion 6 is formed.
